  • Human Influences on the Environment
    • Food Production
      • Greenhouses +polythene tunnels
        • Controls CO2 leves and temperature.
      • Fertilisers
        • Increase of crop yields
      • Pesticides
        • Release of chemicals + kills pests, harmless insects and predators
      • Biological pest control
        • Kills pests, animals and plants
    • Fish Farming
      • Enclosed fish
        • Fast spreading disease
      • Fish waste+ food
        • Water pollution
      • Fish farming food
        • Depletion of Wild fish stocks
    • Air Pollution
      • Fossil fuel burning
        • Sulphric acid rainwater
      • Burning fuels without enough O2
        • O2 lacking heamoglobin
      • Production of Greenhouse gases
        • Greenhouse effect
    • Water Pollution
      • Fertilisers, sewage, detergents
        • Increases Nitrate quantities
      • Increased algae, blocks light, Deaths
    • Deforestation
      • Soil Erosion
      • Water cycle disturbed
      • Increased CO2 in atmosphere
      • More burning= Less O2
